Üzüm Cibresinin Karanfil Çiçeklerinin Vazo Ömrüne Etkileri

Abstract

In carnation, vase life is shortened due to ethylene and water stress, resulting in petal curling, browning, and wilting symptoms. Preservative solutions are used to prolong the vase life of cut flowers in the world, and natural substances with antimicrobial properties have been preferred as preservatives in recent years. It is thought that benefiting from the antimicrobial properties of plant wastes will be beneficial for both the cut flower industry and waste management because they are natural. This research was carried out to determine the effect of grape marc extract (GME) on the vase life of cut carnation. D. caryophyllus cv. 'Baltico' was used as a plant material. The plants were placed in vases containing two different concentrations of GME (100 µL L-1, 200 µL L-1). The vase life, relative fresh weight (RFW), daily solution uptake (DSU), lipid peroxidation, proline content, and antioxidant enzyme activities were measured during and at the end of the experiment. In the study, it was determined that GME was effective on the vase life of cut carnation flowers and GME at 200 µL L-1 concentration (22.67 days) extended the vase life by 6.50 days and 40.2% compared to the control (16.17 days), (distilled water). At the same time, GME was found to be effective on the post-harvest stress mechanisms of cut carnation flowers. GME improved vase life by increasing both DSU, and antioxidant enzyme activities, and reducing RFW loss. It also reduced the accumulation of MDA and proline.
